cfielitz, at first I think BGMR is more a simulation of modern warfare than a game. For BGMR a miniature of vehicle represents one real vehicle and a miniature base of infantry is a 5-10 real life soldiers. In comparison to MSH and CWC the rules are at first view a bit more complex (from the other hand more realistic) and at second view with your datasheets in your hands its easier than it looks. After 3-4 games this is all gone and you concentrate on your tactics and not to the rules. The choices of the army lists are almost endless and they represent armies from all over the world from 1946 to present. The (writing) order system and the communications system are my favorite. Finally I think that BGMR worth the try if you want to "feel" like a commander in a modern battlefield!

don't be put off by the size of the rules – they try to cover everything which is a lot! Start off with a company or two of tanks aside and then add other assets in subsequent games as familiarity grows.
